LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED

Malus domestica

VARIETY DENOMINATION

‘El Niño Gala’

BACKGROUND OF THE INVENTION

‘El Niño Gala’ was originally found by Steven A. McDonald as a bud sport of a tree growing in a cultivated area in his orchard, commonly known as Royal T Farms, 13321 Rd I SW, Royal City, Wash. The original plant originated as a bud sport that had been grown by grafting ‘Royal Gala’ (expired U.S. Plant Pat. No. 4,121) budwood to a Mark rootstock in 1991. More specifically, a number of ‘Kidd's Gala’ trees growing on Mark rootstock were damaged during a storm. These trees with Mark rootstock were each budded with ‘Royal Gala’ budwood. The resulting original plant of my new variety grew from one of these ‘Royal Gala’ budwood grafts. The new tree grew unnoticed until 1996 when the distinct red color of its fruit was apparent.

This new and distinct ‘El Niño’ tree variety has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length, without any variation in genotype. However, the distinctive combination of traits set forth in the description below have been repeatedly observed in the original tree and in asexually propagated progeny and have been determined to be firmly fixed and to be the basic characteristics of this new tree, which in combination distinguishes ‘El Niño Gala’ as a new and distinct variety.

The new variety has been asexually propagated by or at the direction of Steven A. McDonald by grafting onto Emla 26 rootstock. Asexual propagation has been performed at the Royal T Farms in Royal City, Wash.

BRIEF SUMMARY OF THE INVENTION

The ‘El Niño Gala’ variety is distinguished from other apple varieties due to the following unique combination of characteristics:

1. Achieves excellent fruit color with intense dark red stripe over a bright red background. 2. Color is consistent on apples throughout the tree.

The following detailed description is from observations of the original ‘El Niño Gala’ tree and from observations of approximately seven year old asexually propagated ‘El Niño Gala’ progeny that were observed growing in a cultivated area in Royal City, Grant County, Wash. Certain characteristics of this variety, such as growth and color, may change with changing environmental conditions (e.g., light, temperature, moisture, nutrient availability, or other factors). Color descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Color designations are made with reference to The Royal Horticultural Society (RHS) Colour Chart.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

FIG. 1 shows the fruit on one of the new ‘El Niño’ Gala apple trees.

FIG. 2 shows the fruit on a ‘Royal’ Gala apple tree taken at the same time as the photograph of FIG. 1.

FIG. 4 illustrates exemplary fruit of the new variety at harvest maturity on Aug. 29, 2006, showing intense full color with darker stripes.

FIG. 5 illustrates fruit of the new variety and other identified ‘Gala’ cultivars at harvest maturity on Aug. 29, 2006. Specimens were obtained from the original tree of the new ‘El Niño’ variety from an adjacent Royal Gala tree, and from the other selections from orchards located with an 18 mile radius of the original tree of the new variety with similar maturity dates.

DETAILED BOTANICAL DESCRIPTION

The fruit of ‘El Niño Gala’ trees exhibits a size and shape that is typical of ‘Royal Gala’, but has intense dark red stripes over a bright red background skin color. ‘El Niño Gala’ is usually colored by 90-100% red stripes and background. It should be noted that colors may vary, for example due to lighting conditions at the time the photographs are taken. Therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from the photographs alone.

As blooms open, the petals and spur leaves     have a skinny, weak appearance with red pigment on the inside and     outside of the petals. As the blooms continue to open, the petals     and leaves are more similar to ‘Royal Gala’ and ‘Gale Gala’, except     the petals are more reddish or pink. ‘El Niño Gala’, thus far, has     been much easier to blossom thin with lime sulphur than ‘Royal     Gala’.     -   -   Size.13 Medium size, typical flower measuring about 37 mm             across.         -   Bud length.—15 mm.         -   Bud diameter.—10 mm.         -   Petals.—Five petals per flower; about 0.6 (to slightly             larger) inch long and 0.5 (to slightly smaller) inch wide.         -   Stamen.—14 stamens, each about 5 mm long.         -   Pistil.—Stigma: About 7 mm long; 10 styles.         -   Sepals.—About 7 mm long and about 5 mm wide.         -   Bloom season.—In 2006, full bloom was observed in Grant             County, Wash. on Apr. 28, 2006. -   Fruit (unless otherwise noted, from observations of a limited number     of typical fruit in Grant County, Wash.):     -   -   Size.—Medium to medium small, about 3 inches long and about             2-⅞ to 3 inches across; average size of about 2-¾ to 2⅞ to 3             inches.         -   Form.—Oblique to ovate (round conical).         -   Cavity.—Average width is 3.2 cm. Average depth is 1.5 cm.         -   Basin.—About 0.4 to 0.5 inch deep and about 0.75 inch wide.         -   Skin appearance.—Smooth.         -   Stem.—Medium in length, typical average observed in August             of about 0.8 inch to about 1.0 inch long and 0.125 inch in             diameter. Stem is clubbed at the spur attachment.         -   Locules.—Five.         -   Lenticels.—Moderate in number at the basal end and becoming             numerous in number at the apex end. Size range of 0.3-1 mm             in diameter. White.         -   Color.—General Color Effect: Dark red distinct stripe over             red background over typically 95% to 100% of the surface.             Dark red “chimera” over red under-stripes. Little ground             color shows at harvest. As the ground turns from pale green             to yellow in storage, the dark red pigment softens slightly,             but remains distinctively dark red. Color is consistent             throughout the tree. Striped over color is from the greyed             purple group RHS 183A over RHS N34 of the orange red group.             Where undercover is present, it appears to be yellow RHS 8A.             Color development is slow, with the fruit appearing similar             to ‘Royal Gala’ through July with a very dramatic color             change during the final 7- 10 days before harvest. Color             stability is excellent.

Russetting.—About 10% of fruit have varying degrees of stem bowl Russett. Table 1 below shows a comparison table of average chroma and hue as measured by a Minolta colorimeter of the ‘Gala’ cultivars illustrated in FIG. 5 at harvest maturity on Aug. 29, 2006.
